An object of our present invention is to provide a simply and inexpensively constructed ventilating sash which does not require putty for mounting the glass panes therein, grooves being provided for the panes and the panes being slid- V ablerelativ'e thereto for easy removal and replacement, the sash being constructed however so that ventilation can be secured by opening a section thereof, which when closed, provides a substantially'weather tight sash.

Another object is to provide a sash which is very inexpensive, particularly by eliminating the necessity of puttying the glass panes inposition so that the sash may be economically used for 'farm building and other low cost housing installations.

Another object is to provide a sash having a stationary section and a removable ventilating section, both sections having grooves to receive the side edges of glass panes and the upper rails of both sections being relatively thin to permit e of the glass panes thereby during the insertion or removal of the panes relative to the sections.

26 A further object is to provide a sash comprising railsand stiles in which the stiles are of v uniform thickness throughout their height and to provide stationary and ventilating sections which have stiles of similar cross section,

I0 the stiles of the stationary section cooperating with the stiles of the sash to form therewith substantially unitary stiles and the stiles of the ventilating section being a continuation of the stiles of the stationary section whereby the 86 window has a substantially uniform appearance throughout the height of the stiles and the glass panes used in both the stationary and ventilating sections are of uniform size.

Another object is to provide a rabbeted con- 9 nection between the stiles of the ventilating section and the stiles of the sash frame to prevent easy entrance of water through the sash around the ventilating section, a similar rabbeted connection being provided between the sash frame 45 stiles and those of the stationary section whereby uniformity in the cross section of the sash frame, stationary section and ventilating section stiles may be had throughout the height of the window sash.

60 Another object is to provide the top rail of the sash frame and the bottomv rail of the ventilating section with rabbets and to provide a rib of each rabbet to lap outwardly and downwardly over. the top edge of the ventilating sec- 65 tion and stationary section respectively, such ribs providing water shed connections and the rabbeted portions providing shoulders which normally prevent the removal of the glass panes from the ventilating and stationary sections.

Still a further object is to rabbet the lower 5 rails of the ventilating and stationary sections along their upper outer edges, the rabbets being formed with downwardly and outwardly inclined surfaces on which the lower edges of the glass paiies rest and which surfaces drain water 10 away from the panes.

Still another object is to provide the ventilating section removable either bodily or partially by swinging it outwardly on a hinged connection whereupon the glass panes may be removed, the 15 hinged arrangement and hardware for opening the ventilating section and retaining it in various open positions being so designed as to prevent removal of the glass panes except as disengagement of the hardware permits.

Still another object is to provide a ventilating puttyless sash to which screen wire can be applied very inexpensively,the hardware for opening the ventilating section being so designed that there is a minimum of interference between the screen and the hardware, the hardware necessitating the provision of only a small opening in the screen when applied to the sash through which a thrust bar of the hardware may slide.

With the foregoing and other objects in view 30 our invention will be apparent from the following description in connection with the draw; ings. The invention is illustrated by the preferred embodiment thereof shown in the accompanying drawings in which:

Figure 1 is an inside elevation of a ventilating puttyless sash embodying our invention.

Figure 6 is an enlarged sectional view on the line 66 of Figure 1 showing the withdrawal of the glass pane from the ventilating section of the sash; and

Figure 7 1s a sectional view similar to the 6 the reference characters I. and I2 to indicate the stiles and top rail of a window sash frame. A fourth rail |3 completes. the sash frame,

Within the sash frame a lower stationary section and an .upper ventilating section are provided. The stationary section comprises the rail 13, a top rail l4, stiles 'II and a muntin i6. .The ventilating section comprises bottom and top rails I1. and I3, stiles |3 and-a muntin 23. The stationary and ventilating sections are completed by glass panes 2| and 22 respectively. The stiles III are of the same cross section throughout their height as shown in Figures 2 and 3. They are rabbeted as illustrated at 23 while the stiles l3 and I9 are reversely rabbeted as at 24. The stiles l5 cooperate with the stiles III to form a unitary stile for the stationary sash section, the rabbets 23 and 24 in Figure 3 being shown assembled tightly together and retained in assembled position by tenons 26 of the rail l4 extending into mortises of the stiles |6.. The lower ends of the stiles l0 and I6 are slotted to receive tenons |3a on the ends of the bottom rail l3. The rabbets 23 and .24 along the stiles IQ of the ventilating section are provided with clearance as shown in Figure 2 so that the ventilating section may be readily removed or swung outwardly in case the ventilating section is hinged as shown in Figure 4.

The stiles I5 and I9 and the muntins l6 and 26 are grooved as indicated at 26 to slidably receive the side edges of the panes 2| and 22. The ends of the muntins l6 and may be provided with tenons 21 to fit in mortises 28 of the rails l3, l4, l1 and I3. The outer upper edges of the rails 3 0 and I! are rabbeted so as to provide sloping shoulders 29 against which the lower edges of the panes 2| and 22 rest as illustrated in Figures 4.

and 5. These shoulders support the glass panes and effectively shed water therefrom.

Thte lower edges of the rails l2 and l I are rabbeted whereby ribs 36 are provided as shown in Figure 4. The ribs 30 lap over the upper edges of the stationary and ventilating sash sections and over the upper edges of the panes 2| and 22 to provide water sheds and thereby prevent water from running inside the panes. The rails l4 and I8, it will be noted, by reference to Figure 4 are of less thickness than the stiles l6 and I3 so that the panes 2| and 22 can he slid past them 55 when entering the grooves 26.

In Figure 4 I have shown hinges 3| on the outside of the window attached to the rails l2 and i3 for mounting the ventilating section of the Hardware is provided in the form of a 60 bracket plate 32 and a thrust bar 33 together with a second bracket plate 34 and a hinge Pl 35 for adjusting the degree of opening of the ventilating section relative to the sash frame.

The bracket plate 32 has an opening 36 formed 65 therein through which the thrust bar 33 may be slid. A finger 31 extends upwardly from the bottom of the opening 36 for selective coactio'n with one of a pluralityof spaced perforations 38 in the thrust bar 33. Such ,a position of adjust- 7Q ment is shown by dotted lines in Figure 2 and by dotted lines-in Figure 4- wherein the ventilating section is only slightly opened. v

The hinge plate 35 is pivoted on a pin 39 car- "ried by ears 40 of the bracket plate 34. The ears 7 46 are located in a socket 4| formed in the .lower rail ll of thevsntilating sash section. The thrust bar 33 is pivoted to the hinge plate 3| by a rivet 42. The pivot pin 33 permits various degrees of inclination of the thrust bar 33' relative to the plane of the ventilating sash section as shown by dotted lines in Figure 4 while the rivet 42 permits movement of the thrust bar 33 from the dotted position of Figure 2 when the ventilating sash sectionis open to the full line position thereof when the ventilating section is closed. The edge of the thrust bar then engages the bracket plate 32 to retain the ventilating sec-' tion in closed position. A hooked end 43 on the thrust bar 33 may be sprung into position behind the head of a screw 44 mounted in one of the stiles IE to retain the thrust bar in its locked pos ition substantially parallel to the plane of the window. I

The upper ends of the grooves 26 for the panes 2| and 22 are open so that the panes can he slid upwardly for removal. In the closed position of the ventilating sash section however it is obvious I that the panes cannot be removed. When the sash is swung to open position, the edges of the thrust bar 33 as shown by dotted lines in Figure 25 2 overlap the edges of the panes 2| so that they cannot be removed while the panes 22 cannot be removed because ofthe upper rail l2 of the sash frame. By swinging the ventilating section to the position of Figure 6, however, the panes 22 30 can he slid out for renewal purposes. This position is possible only by disengaging a portion of the hardware such as the bar 33 from the bracket plate 32 as shown by dotted lines in Figure 4.

A notch 33a in the side of the bar 33 permits the bar to be raised out through a slot 32a in the top of the plate 32. The slot is narrower than the body of the bar. a

In some instances it may not be desirable to provide the hinges 3|, but merely have the ventilating section of the sash entirely removable. This can be accomplished by placing a plurality of turn-buttons 45 on the rails and stiles l1, l3 and I9 as shown in Figure 7 to retain the ventilating section of the sash in position when the buttons are turned to the position shown. They may be rotated a quarter of a turn for permiting removal of the ventilating sash section. When the ventilating section is removed, of course, then the panes maybe withdrawn from it and from the stationary section also.

The screening of our window structure is comparatively simple. The screen wire is shown at 46 in Figure 1 and consists of a rectangular piece which may be tacked or otherwise secured to the sash frame. To avoid confusion on the drawing only a portion of the screen is shown and the remaining outline of the screenis shown by dot and dash lines. Also a rectangular opening 41 in the screen is shown by dotted lines in this figure and by solid lines in Figure 5. This opening 41 surrounds a portion of the bracket plate 32 so that the screen does not interfere with passage of the thrust bar 33 therethrough.

To facilitate replacement of the glass panes 2| and 22, the screen 46 should'be readily removame. We have accordingly shown molding strips 48 to retain it in position and screws 43 for se-' curing the molding strips to the sash frame.

From the foregoing description of our window structure, it will be obvious that we have provided one in whichthe glass panes are assembled with a minimum of expense for material and labor. The grooves 26 receive the edges of the glass panes 2| and 22 so that they can be readily removed,

I A amass-r such removal, however, being impossiblewhen the window is closed. The hardware and upper rail of the sash frame are so designed and associated with the structure that the panes ofglass can be removed only by adjustment of the hardware and ventilating section to predetermined non-normal positions. The cross sectional shapes of the various parts are so designed that the as for the ventilating section. When the ventilating section is placed-in the sash frame and is in closed position it is flush with the opposite faces thereof and a succession of overlaps and glass panes provide a water shed from top to bottom of the assembled unit. Removal of the panes is had only by adjustment of the parts of the'sash to a predetermined relationship and all panes of glass in the window may be of uniform size. The window, of course, may be built in several styles with different numbers and arrangements of glass panes and ventilating sections. Also our window is readily screened without interference of the screen with the operating hardware.
